This invention relates to carburetors. Objects of this invention are to PIOVldB a novel form of carburetor which is. so constructed that it will .normally wash the air by passing the air through water prior to erence characters 6 and 7, (see Figure 4:).

its arrival at the mixing chamber, and which is so made that it will allow the thorough moistening of air by means of a heated water nozzle connected with a water supply chamber through Which the air is normally passed.

' Further objects are to provide a fuel nozzle and a water nozzle both located in the mixing chamber and each heated by means of an electricheater surrounding the nozzle, so that the heating of the nozzle may be controlled and may be utilized in starting, for instance, or during other \conditions where heat at this point is required.

Further objects are to provide a-carburetor which is compact, which is provided" with a fuel reservoir and a wat'er reservoir, which is provided with electric heating means for 192s. Seria1 No. 314,961..

'1 terminal 5 connected thereto, the otherside of the heaters being grounded.

Within the mixing chamber, a pair of nozzles are located, as indicated by the ref- The nozzle 6 is a water nozzle and isconnected by means of the passageway 8 with the water reservoir 3. This passageway is controlled by a thermostatic valve 9, so that when the water arrives at the proper temperature, it will open, otherwise, the Valve remainsclosed. The fuel nozzle 7 is connected to the fuel reservoir- 2 by means of the passageway 10 (see Figures 2 and '5).

The nozzles 6 and 7 are controlled by ad-v justable needle valves 11 and 12, respectively.

The water reservoir is supplied .frolnany suitable source by means of the pipe 13, and the height of the water is controlled by thevalve 14 operated from the float 15. The height of the fuel in the fuel reservoir 2 is controlled by the fioat 16 which controls the valve 17. The valve, in turn controls the heating the fuel reservoir, and which is also flow through the supply pipe 18. 5 provided with an exhaust gas jacket for heating both reservoirs, that is, the gas and the water reservoirs, suchheating being controlled by a thermostatic valve so that after the engine operates a certain length of time,

The water and fuel reservoirsare provided with drain valves 19 and 20 respectively (see Figure 3). A heating jacket .21 is positioned below the two reservoirs and is adapted to receive exhaust gases from the engine so as to 9 the temperature isautomatically controlled. maintain the reservoirs warm. The temper- An embodiment of the invention is shown in the accompanying drawings in which:

Figure 6 is a view of the underside of the cover for the water reservoir, the air pipes being in section.

Referring to the drawings, it will be seen that the carburetor comprises a mixing chamher 1, a fuel reservoir 2, and a. yvater reservoir 3. The fuel reservoir is provided with ature'is controlled by means of a thermostatic valve 22 which cuts-off the flow of the exhaust gases when the temperature arrives at a predetermined poin'tl If desired, a by-pas s pipe 23 may extend from a duct 24 leading to the fuel reservoir 2, as shown in F igures 4 and 5. Thispipe leads to an idler valve 26 (see Figure 4) I which opens above the throttle valve 27.

The normal air intake is indicated by the a pair of electric heaters 4 which have "a or passageway 32 which opens into the conduit 33, such latter conduit or passageway opening into the lower portion of the mixing chamber, as shown most clearly in Figures land 2.

Further, an auxiliary air inlet 34 is pro vided (see Figures 1 and 2) and the flow of air through this inletis controlled by the auxiliary air valve 35. The air valves 31 and 35 are controlled by means of rods 36 and 37,

-trol of the condition respectively, which lead to any suitable point accessible to the operator. A similar construction is employed for the throttle valve, I such throttle valve rod being indicated by the reference character 38.

Thus, the operator is enabled to readily control the direction of air flow entering the apparatus. For instance, he may permit the air to enter through the air inlet 28 in which case the air will pass downwardly through the water in the water reservoir, and will be 2. A carburetor comprising a fuel reservoir, a water reservoir, a heating jacket adjacent said reservoir and adapted to receive exhaust gases, a fuel and a water nozzle connected to the respective reservoirs, means for heating said nozzles, spaced electrical heaters arranged within said fuel reservoir, and a mixing chamber within which said nozzles are located.

thoroughly washed and will thereafter pass 7 to the mixing chamber, By closing the inlet 28 and opening the inlet 34, this washing of the air is stopped and the air, is permitted to enter through the auxiliary air inlet 34:

From reference to Figure 4 it will benoted. thata by-pass member 39 is provided between the upper portion of the water reservoir and the mixing chamber 1. This opening is above the nozzles, as is apparent from the figure. The opening pei'mits the passage of moisture laden air into the mixing chamber.

7 Thus, the'operator is enabled to co1 1troLv the incoming air. In addition to this, he is able to control both the heating of the fuel within the fuelreservoir 2 and also the heating of the nozzles 6 and 7 t This wide flexibility of control enables the operator to secure avariety of combinations for the carburetor, depending upon the conditions of temperature. and humidity of the outside air and also depending upon the temperature of his engine.

It will be seen thata carburetor, lfasbeen provided which is very compact although having the characteristics discussed in detail i has been-describeiR voir, a water reservoir,.a heating jacket adjacent said reservoirs and adapted to receive exhaust gases, a fuel and a water nozzle coilnected to the respective reservoirs, electric heaters surrounding said nozzles, an electricheater within said fuel reservoir, and a mixing chamber within which said nozzles are located.
